We have three MSDN developer  webcasts this week covering the .NET Framework:

 

MSDN Webcast: Transactional Windows Communication Foundation Services with Juval Lowy (Level 200)

Transactions are the key to building robust, high quality service-oriented applications. Windows Communication Foundation (WCF) provides a simple, declarative transaction support for service developers, enabling you to configure parameters such as enlistment and voting, all outside the scope of your service. In addition, WCF allows client applications to create transactions and to propagate transactions across service boundaries over a variety of transports. In this webcast, we explain how to configure transaction flow at the binding, contract, and service level, local versus distributed transactions, setting of service transactions, declarative voting, and the available configurations that best fit various application scenarios. Presenter: Juval Lowy, Principal and Software Architect, IDesign

7/7/2008 10:00 AM - 11:15 AM Pacific Time (US & Canada)| Duration: 75 Minutes

MSDN Webcast: Using Windows Workflow Foundation to Build Services with Jon Flanders (Level 300)

Windows Workflow Foundation (WF) is a programming model, set of tools, and runtime environment which allows you to write declarative and reactive programs for Windows operating systems. WF is part of the Microsoft .NET Runtime, and it first appeared in Microsoft .NET 3.0. Windows Communication Foundation (WCF) is also a programming model, set of tools, and a runtime that first appeared in .NET 3.0. WCF is a framework for building applications that can communicate with each other over varied network protocols. In .NET 3.5, these programming models came closer together to allow easy integration, including allowing WF instances to use WCF to communicate to remote endpoints and allowing WF instances to become the service implementation for WCF endpoints. This is accomplished by two new Activities: ReceiveActivity and SendActivity as well as a new hosting infrastructure for service endpoints. In this webcast, we look at both sides of this integration to give you an overview of how to build WF/WCF applications. Presenter: Jon Flanders, Consultant, Pluralsight

MSDN Webcast: WCF Extensibility Deep Dive with Jesus Rodriguez (Level 400)

Windows Communication Foundation (WCF) provides a rich messaging framework that extends beyond its capabilities for modeling and implementing services. One of the aspects where WCF really shines when compared with competitive Web services stacks is its rich extensibility model that allows developers to customize the default behavior of the framework. The better we understand the WCF extensibility model the better chance we have to make the right use of WCF in real-world applications. In this webcast, we dive deeply into the WCF extensibility model, detailing the different extensibility points of WCF subsystems such as Channels, Hosting, Security, Metadata, Encoding, and others. Specifically, we provide practical demonstrations of how custom channels, behaviors, operation invokers, authorization managers, and metadata extensions can be used to extend WCF effectively without affecting the consistency of the programming model. We also highlight a set of best practices developers should consider to address their specific scenarios properly when extending WCF. Presenter: Jesus Rodriguez, Chief Architect, Tellago, Inc.
